## Long description

ROLINE 21.17.0052 is an SC-to-SC fibre optic adapter with female SC connectors designed for OS2 single-mode fibre. The compact keystone-format adapter ensures accurate ferrule alignment and low insertion loss when mating SC connectors, making it suitable for use in splice panels, patch panels and other fibre optic equipment in telecom and data network installations. The adapter is lightweight and intended to provide reliable, passive coupling between single-mode jumper cables.
Advantages
The adapter features a high-quality plastic housing in a keystone format that simplifies installation into front plates and chassis. An internal ceramic sleeve provides precise ferrule alignment and wear resistance, reducing signal loss and preserving connector end-face integrity. Its female SC/SC configuration enables straightforward extension or re-connection of single-mode fibre jumper cables without additional tooling.
Suitable for
Single-mode OS2 fibre patching in telecom and data networks
Insertion into keystone front plates, patch panels and chassis
Extending or joining SC-to-SC single-mode jumper cables
Splice and distribution enclosures requiring passive SC coupling
Key specifications
Connector configuration: female SC to female SC (SC/SC)
Fibre type compatibility: OS2 single-mode fibre
Housing format: keystone-format plastic housing
Ferrule sleeve material: ceramic
Typical application: passive mating of single-mode jumper cables and installation in front plates or patch panels
Weight: 4.6 g
How to use
Install the adapter into a compatible keystone aperture in a front plate, patch panel or chassis until it locks securely. Align and insert the SC single-mode jumper cable ferrules into each side of the adapter until an audible or tactile click is felt, ensuring end-faces are clean and undamaged prior to mating. For removal, depress the connector latch and withdraw the cable straight out to avoid stressing the fibre.
Usage recommendations
Inspect and clean connector end-faces with appropriate fibre cleaning tools before each connection to maintain low insertion loss. Use the adapter indoors or in protected enclosures; avoid exposing it to prolonged moisture, dust or mechanical impact. Match the adapter to OS2 single-mode jumper cables and avoid mating single-mode to multi-mode fibres to prevent increased loss or back reflections.
